description:
    This package provides an implementation of library modules to be defined by the future Haskell2020 Library Report.
    .
    __NOTE__: The Haskell2020 Library Report has not yet been released and therefore this implementation is merely a technical preview and subject to change.
    .
    == Changes relative to Haskell2010
    .
    * [Remove Show/Eq superclasses of Num](https://mail.haskell.org/pipermail/libraries/2011-September/016699.html)
    * [Remove Num superclass of Bits](https://mail.haskell.org/pipermail/libraries/2011-October/016899.html)
    * [Add Bits instance for Bool](https://ghc.haskell.org/trac/ghc/ticket/7424)
    * Add 'Monad' instance for @(->)@ and 'Either'; add 'Functor' instance for @(,)@
    * [Export Word from Prelude](https://mail.haskell.org/pipermail/libraries/2014-August/023491.html)
